It is the main heat exchange to cool or heat the air . It can heat the air with high temperature water, steam or high temperature heat conduction oil, and cool the air with salt water or low temperature water.
Finned Tube is a kind of ribbed wall, many spiral heat exchange surface or threaded tube can also be regarded as finned tube. It plays a significant role in expanding the heat transfer area and promoting turbulence, both for single-phase and phase transition convection heat transfer. Finned tube heat exchanger structure is basically the same with general Shell And Tube Heat Exchanger , but with finned tube instead of flat tube as the heat transfer surface, because of heat transfer enhancement and compact structure, it can be made into a compact heat exchanger.
The Finned Tube Heat Exchanger includes Spiral wound type Air Heat Exchanger, Extruded type air heat exchanger, String type air heat exchanger, High frequency welding air heat exchanger,etc. There are many types of finned tube, we can select the suitable type based on the operating conditions and mediums` characteristics.

In 2013, the development of the LED industry, the beauty and the thorns are in the same place. With the advent of the LED lighting era, the manufacturers have not earned a lot of money, and the shadow of increasing revenues without increasing profits is lingering. In 2014, the growth performance of the LED lighting market is expected, and the industry reshuffle and the strong and strong pattern will continue.
According to statistics, in the second half of this year, the LED lighting market has begun to grow rapidly and is expected to continue its five-year high growth. As for the benign development of the LED industry, the profits of the downstream brands are relatively good; the upstream is over-invested and the oversupply of production capacity. In addition, during the three years from 2010 to 2013, the average annual decline in the price of LED lighting products exceeded 20. In 2012, the output value of LED indoor lighting in China reached more than 30 billion yuan. In 2013, the market size reached 63 billion yuan.
Industry analysts believe that the most important trend in the LED lighting market in 2014 is that the lighting industry will shift from brand-scale economy competition to manufacturing economies of scale plus brand-scale economies of scale, which will make the industry concentration of LED lighting era more traditional. High illumination. Among them, the domestic market in the domestic market is concentrated in the commercial lighting field, and alternative light sources and downlights are gradually becoming mainstream shipments. From the export data, the growth rate of LED lighting products is accelerating, and the export performance in the fourth quarter is not weak.
At the same time, the National Development and Reform Commission previously issued the "Notice on Strengthening Work to Ensure the Implementation of the Energy Conservation and Emission Reduction Targets in 2013". The National Development and Reform Commission, the Ministry of Finance and the Ministry of Housing and Urban-Rural Development are jointly responsible for promoting the implementation of green lighting projects and continuing to implement energy-saving products. In the future, the financial subsidies for green lighting will shift from fluorescent lamps to high-efficiency lighting products such as LEDs.
Experts predict that with the withdrawal of state subsidies and the increase in demand for LED lighting, the LED chip industry will improve in 2014, and the entire market is expected to usher in a turning point in the second half of the year.
